Abstract
The present invention provides methods and devices for high sensitivity and high speed microarray optical imaging. The methods include using patterned excitation to obtain a series of images and analyzing the images to resolve probe intensities which reflect the hybridization or binding between target and probes. Probe feature information and patterned excitation (structured illumination) information are incorporated into the analysis.
Claims27
A system comprising a processor;
- and a memory coupled with the processor, the memory storing a plurality of machine instructions that cause the processor to perform logical steps of the method comprising obtaining a series of fluorescent images of a microarray, wherein the fluorescent signals reflect binding between targets and probes, and wherein each of the images is obtained with a different excitation pattern;
- and
- Analyzing said images using calibrated information about said different excitation patterns to obtain intensities for each of said probes.
